SelectFilter default not working

I am trying to set a default value on my SelectFilter:

SelectFilter::make('status')
    ->multiple()
    ->options(RefundStatus::class)
    ->default(RefundStatus::Pending),

SelectFilter::make('status')
    ->multiple()
    ->options(RefundStatus::class)
    ->default(RefundStatus::Pending),

SelectFilter::make('status')
    ->multiple()
    ->options(RefundStatus::class)
    ->default(RefundStatus::Pending),

SelectFilter::make('status')
    ->multiple()
    ->options(RefundStatus::class)
    ->default(RefundStatus::Pending),

This is about the same as in the docs, instead the docs use a string value.

Solution

Make sure you use

RefundStatus::Pending->value

RefundStatus::Pending->value

RefundStatus::Pending->value

RefundStatus::Pending->value.
